Peroxiredoxin 4 Involved in Spermatogenesis by Affecting Oxidative Stress and Ferroptosis

Andrology, EarlyView.
ABSTRACT Background The main functions of testes are sperm production and androgen secretion in testicular befitting microenvironment. Excessive level of the reactive oxygen species (ROS) from metabolism and cellular events can lead to oxidative stress (OS) and ferroptosis, which injure the functions of mitochondria and endoplasmic reticulum (ER) of ...

Testis‐Enriched F‐Box Protein FBXO39 Is Important for Spermiogenesis and Male Fertility in Mice

Andrology, EarlyView.
ABSTRACT Background The SCF (Skp–Cullin–F‐box) complex is a major class of E3 ubiquitin ligases. F‐box proteins constitute the SCF complex and play a critical role in recognizing substrates for ubiquitination. In mice, several F‐box proteins, including FBXO36 and FBXO39, are predominantly expressed in testes.

Boosting Male Fertility: The Impact of Gonadotropin Therapy on Hypogonadotropic Hypogonadism—A Systematic Review and Meta‐Analysis

Andrology, EarlyView.
ABSTRACT Background Male hypogonadotropic hypogonadism typically presents with azoospermia and is one of the few causes of infertility amenable to a medical intervention. Gonadotropin therapy offers a chance to restore spermatogenesis and fertility in these individuals.

Cyclic Treatment With WIN 18,446, a Potential Male Contraceptive, is as Effective as Continuous Treatment for Suppression of Spermatogenesis in Mice

Andrology, EarlyView.
ABSTRACT Background Retinoic acid plays a critical role in spermatogenesis during both spermatogonial differentiation and spermiation. Mice lacking enzymes that synthesize retinoic acid, Aldh1a1/1a2, in the testes are infertile. WIN 18,446 reversibly inhibits spermatogenesis by inhibiting ALDH1A1/1A2 and is a promising approach to male contraception ...

Improvement of Mouse Spermatozoa Freezing at ‐80°C With Ascorbic Acid 2‐Glucoside at Thawing Phase

Andrology, EarlyView.
ABSTRACT Background Sperm cryopreservation is the most common method to maintain a great number of mutant mouse lines. However, the use of liquid nitrogen (LN2) for freezing presents considerable problems in terms of cost, safety, and accessibility. For this reason, the storage of semen samples at ‐80° in ultra‐freezers has been increasingly used in ...
